Interface CSSRule

All Known Subinterfaces:
CSSCharsetRule, CSSFontFaceRule, CSSImportRule, CSSMediaRule, CSSPageRule, CSSStyleRule, CSSUnknownRule
public interface CSSRule
The CSSRule interface is the abstract base interface for any type of CSS statement. This includes both rule sets and at-rules. An implementation is expected to preserve all rules specified in a CSS style sheet, even if the rule is not recognized by the parser. Unrecognized rules are represented using the CSSUnknownRule interface.

See also the Document Object Model (DOM) Level 2 Style Specification.

Since:
1.4, DOM Level 2

    • getType

      short getType()
      The type of the rule, as defined above. The expectation is that binding-specific casting methods can be used to cast down from an instance of the CSSRule interface to the specific derived interface implied by the type.
